Its a big hassle to find someone to take over your lease.
You want the M3, dealer will eat the take over, what's the problem?
I had same experience about 4 years ago.
I had leased 128i and wanted to get 335 so I went to the dealer and they gladly took my lease over and I bought 335. Yes no discount were given, yes I got my security deposit back. The point is I went to like 5 non BMW dealership and they all wanted me to shell out at least $4000~5000 for them to take over.
Go see your dealer, leave your 435xi and pick up the M3 asap!
